Methods, systems, and computer readable media can be operable to encode an input video stream into one or more output streams by using information obtained from a first transcoding of the input video stream. During a first encoding of an input video stream, pre-processing, motion estimation, mode decision, and other information can be collected or buffered and can be re-used to encode the input video stream to multiple output video streams at different bitrates, resolutions, and/or frame rates. Motion estimation, macroblock mode decision, and pre-processing data can be manipulated and re-used during the encoding of an input video stream at various resolutions. Data can be re-computed at a new resolution or bitrate to improve visual quality.

Adaptive bit rate co-operative transcoding

Methods, systems, and computer readable media can be operable to reduce the number of video streams or increase the quality of delivered video with the same number of video streams in a multiple bitrate video encoding. Multiple video resolutions and/or frame rates can be combined into a single stream. In embodiments, optimal segments from a plurality of input streams can be selected for inclusion in an output stream based upon a range of acceptable quantization parameter values for the output stream and a quality characteristic associated with the optimal input stream.

Multiple stream video compression in multiple bitrate video encoding

Methods and systems for integrated transcoding on a plurality of data channels to convert one or more data channels from an incoming encoding format to an outgoing encoding format are disclosed.
